The Professional Group is latest firm to relocate headquarters from suburbs to downtown Detroit

DETROIT, MI – The Professional Group (TPG) is moving its corporate headquarters and the 65 employees based there from Southfield to downtown Detroit, the company announced Tuesday.

The building maintenance and janitor services firm will lease 15,200 square feet of space on the 21st floor of the Chrysler House from Bedrock Real Estate Services, the real estate firm under the umbrella of Quicken Loans founder Dan Gilbert’s Rock Ventures.

“Being in the heart of Detroit will allow us to expand our network in a way that is beneficial for our team, our clients and our city,” TPG President Doug Hamburger said in a statement.

“This move represents an opportunity to reconnect with the energy and revitalization of a great American city,” Joseph Ciolino, chief financial officer of BELFOR Holdings, said in a release.

Rock Ventures bought the Chrysler House, formerly known as the Dime building, in 2011.

“The Professional Group is the latest service provider to recognize the growing number of companies doing business in downtown Detroit who need services that TPG offers,” said Jim Ketai, managing partner, Bedrock Real Estate Services.

TPG will make the physical move in August.

In May, international architecture firm Rossetti announced it is moving its headquarters from Southfield to downtown Detroit. The firm is moving its 60 architects, planners and designers into 13,000 square feet of space at the 172,000-square-foot, Rock Ventures-owned Federal Reserve building next month. The building, at 160 Fort St., has been vacant since 2004.

Last July, Title Source, a Rock Ventures company, announced it was moving its 1,500 employees to downtown Detroit.

Quicken Loans, too, was based in the suburbs until Gilbert moved its headquarters to downtown Detroit in 2010, setting off a series of investments in the city's core that so far show no sign of slowing. Around the same time Quicken Loans decided to move, Blue Cross Blue Shield announced it was moving 3,400 workers from Southfield to downtown Detroit.
